Customer Question

Can you please give me at least two strategies for solving the following math problems?

(520)(69) and 452+721+908

Another way of solving rather than the traditional algorithm? Thanks

 

Optional Information:
Level/Year: College
Subject: Math

Already Tried:
for the addition: 400+700+900=2000 then, add the tens column, 50 + 20 = 70, then the ones column, 2+1+8=11 total 2081. However, this is the only one I can think of. The other problem (520)(69) I'm not sure ...maybe adding?

hello,

 

are you just looking for ways you could consider doing these on paper?

 

Customer replied 317 days ago.

Not only the paper and pencil method, but with other manipulatives such as blocks, beads, etc.
